(rate1/rate2) = sqrt(M2/M1)
M2 = molar mass of gas 2. M1 = molar mass gas 2.
Under certain conditions, neon (Ne) gas diffuses at a rate of 4.5 centimeters per second. Under the same conditions, an unknown gas diffuses at a rate of 10.1 centimeters per second. What is the approximate molar mass of the unknown gas?

Ne = 20.2
mv^2 = const
m ~ 1/v^2
(4.5/10.1)^2 = 0.198
20.2 * 0.198 = 4.0 g/mol (Helium)
mv^2 = const
m ~ 1/v^2
(4.5/10.1)^2 = 0.198
20.2 * 0.198 = 4.0 g/mol (Helium)
that is an incorrect answer
